💡 What: surveyFA.Rselect_bad_item 함수 내에서 최솟값 탐색을 위해 사용되던 names(sort(x))[1L]names(x)[which.min(x)]로 변경했습니다.
🎯 Why: 기존에 사용하던 sort() 기반 최솟값 탐색은 매번 불필요한 전체 정렬을 수행하여 O(N log N)의 시간 복잡도 오버헤드를 유발하고 있었습니다. which.min()은 단일 패스(선형 탐색)만으로 최솟값의 인덱스를 찾으므로, 이를 사용하여 O(N)으로 성능을 최적화했습니다.
📊 Impact: p_values 벡터의 크기 N에 비례하여 최솟값 탐색 속도가 크게 향상됩니다. 정렬 오버헤드가 완전히 제거되어, 공통 문항이 많거나 후보 항목이 수없이 많은 경우 CPU 사용량 및 병목이 줄어듭니다.
🔬 Measurement: Rscript -e "testthat::test_dir('tests/testthat')"를 실행하여 모든 단위 테스트가 통과하는 것을 확인했습니다. 함수 기능상의 변화는 없으며, 성능만 개선되었습니다.

👋 Jules, reporting for duty! I'm here to lend a hand with this pull request.

When you start a review, I'll add a 👀 emoji to each comment to let you know I've read it. I'll focus on feedback directed at me and will do my best to stay out of conversations between you and other bots or reviewers to keep the noise down.

I'll push a commit with your requested changes shortly after. Please note there might be a delay between these steps, but rest assured I'm on the job!

For more direct control, you can switch me to Reactive Mode. When this mode is on, I will only act on comments where you specifically mention me with @jules. You can find this option in the Pull Request section of your global Jules UI settings. You can always switch back!

New to Jules? Learn more at jules.google/docs.


For security, I will only act on instructions from the user who triggered this task.

Warning

Review limit reached

@seonghobae, you've reached your PR review limit, so we couldn't start this review.

Next review available in: 1 minute

Enable usage-based reviews in Billing to review now. Otherwise, wait until the next included review is available.
You're only billed for reviews past your plan's rate limits ($0.25/file).

How can I continue?

After more reviews become available, a review can be triggered using the @coderabbitai review command as a PR comment. Alternatively, push new commits to this PR.

To avoid repeated limits, reduce automatic review volume by pausing incremental auto-reviews earlier, using label-based review opt-in, excluding WIP or generated PR titles, or requesting reviews manually when the PR is ready. If your team needs uninterrupted high-volume reviews, an organization admin can enable usage-based reviews.

How do review limits work?

CodeRabbit enforces per-developer PR review limits for each organization. Most developers receive the normal plan review availability.

For paid Pro and Pro+ PR reviews, CodeRabbit uses adaptive limits for sustained high-volume activity. When a developer's recent PR review activity reaches the 95th percentile or higher among CodeRabbit users, additional reviews become available more gradually as earlier reviews age out of the rolling window.

Please refer docs for additional details.

Pull request overview

OpenCode cannot approve yet because required coverage evidence did not pass.

Review outcome

1. HIGH .github/workflows/opencode-review.yml:1 - Coverage evidence did not prove required test/docstring evidence

  • Problem: The required coverage-evidence job result was failure, so OpenCode cannot establish approval sufficiency for this head.

  • Root cause: Automated approval is only valid when the same-head coverage-evidence job proves supported repository test suites passed and configured docstring gates passed or were advisory, or reports not applicable because no supported source files or package manifests exist. Missing, failed, skipped, unavailable, or unsupported-tooling test evidence is a blocker.

  • Fix: Install or configure the repository test/docstring evidence tooling when source files or package manifests exist, rerun the current-head coverage-evidence job, and approve only after it reports success with required evidence or explicit no-source not-applicable evidence.

  • Regression test: Keep the approval branch checking needs.coverage-evidence.result == success before posting APPROVE, and publish REQUEST_CHANGES when coverage-evidence blocker states such as cancelled, skipped, failed, unsupported-tooling, or below-100 evidence are present.

  • Result: REQUEST_CHANGES

  • Reason: coverage-evidence result was failure, so required test/docstring evidence was not proven for current head 75df8a449a4caa391fd7a44b4717a881888a2915.
